Moment Analysis of Process J/ψ → ρηπ and 1-+ Exotic Hybrid

  • Does an exotic 1-+ hybrid candidate ρ (1405) in the vicinity of a2 (1320) exist? It is worth to confirm this state in the process J/ψ → ρηπ at the BEPC (Beijing Electron-Positron Collider)/BES (Beijing Spectrameter). Considering ρ (1405), a2 (1320) and a0 (1450) overlap in this mass region, the three-state coupling structure mode is discussed by using the generalized moment analysis method. A series of moments for the mode and a criterion are given for confirming the exotic 1-+ hybrid.
